[1]}: “As the datasets are not only multi-class but also multi-label,
we usually need a thresholding method to test the results. But literature gives
a negative opinion of arbitrarily choosing thresholding methods because of the
considerably different performances. To avoid this, we assume that the number of
the labels is already known in all the test processes.”

that the number of labels for test data is given [4]}, [3]}.”
